SPRINKLER.

Specification of Letters Patent.

Patented Nov. 11, 1913.

To all whom, it may concern:

Be it known that we, JOHN S. HADDEN, a subject of the King of GreatBritain, and FREDERICK H; JOHNSON, a citizen of the United States,residing, respectively, at

Huntington Park, in the county of Los Angeles and State of California,and at South Pasadena, in the county of Los Angeles and State ofCalifornia, have jointly invented new and useful Improvements inSprinklers, of which the following is a specification.

This invention relates to sprinklers, and more particularly tosprinklers for lawns and the plant life of gardens and the like; and ithas for its objectto provide a sprinkling device of this generalcharacter which will effectively distribute the water supplied theretoover a relatively wide area with a satisfactory degree of uniformity;and which sprinkler device will be generally superior in point ofrelative simplicity and ful provision, formation, combination, asso- Iciation and relative arrangement of parts, members and features, all ashereinafter described, shown in the drawing, and finally pointed out inclaims.

device or lawn sprinkler, A designates a In the drawing -Figure 1 is aside elevation of a lawn sprinkler constructed and organized inaccordance with the invention;

Fig. 2 is a vertical transverse sectional view of the same, parts beingin elevation; Fig. 3 is a horizontal transverse sectional view of thesame, taken upon the line m w'-", Fig. 2, and looking. in the directionof the appended arrows. Fig. 4 is a top plan view of the sprinkler shownin the other figures; and,

Fi 5 is a bottom plan view of the same.

orresponding parts in all the figures are designated by the samereference characters.

Referring With-particularity to the drawing, in which the invention isshown specifically as embodied in a lawn sprinkling shell, casing orhousing within which the several working parts of the sprinkler arecontained, and which is annular in form and provided with an uppercircular orifice 6 and a lower circular orifice 7. The shell A ispreferably contracted throughout a portion of its extension above thelower orifice 7 as at 8, within which contracted portion screw threads9* are formed for uniting the shell with a similarly threaded union ornipple connected with or upon a water supply main or pipe (notshown).Within the shell A are housed three relatively adjustable members 13, Cand D, the first of which consists of a tubular body 9 having betweenits bottom and top portions screw threads 10 which co-engage with screwthreads 11 formed interiorly of the shell A. The tubular body 9 has anenlarged upper end portion or head 12, producing an annular shoulder 13between which and an annular shoulder 14 produced in the inner wall ofthe shell A above the threads 11 is received a washer 15 producing awater-tight joint between the body 9' and the shell A. The head 12closes the upper end of the tubular body 9 with the exception of thecentral portion thereof in which is produced an outlet or dischargeopening 16 of countersunk formation, whereby the walls 16 thereof flareoutwardly and u warclly in predetermined angularity. Suitablediametrically opposed recesses 17 are produced in the head or top 12 ofthe body 9 for the reception of a suitable implement for connecting anddisconnecting the body 9 and the shell A at the screw threads 10 and 11.

The body 9 is provided with interior screw threads 18, and the member 1)is adjustably connected with said screw threads 18, such membercomprising a cylindrical core or body 19 upon which are produced ordlsposed helical walls or flanges 20 and 21 each of which extends forsomewhat less than one complete turn around the core or body 19, thelower ends or termini of said flanges or walls being approximatelyd1ametrically opposed and the upper ends or termini of said flanges orwalls being approximately diametrically opposed, both flanges or wallsbein of the same pitch, screw-fashion, in their production ordevelopment around the core or body 19. Two helical passages are thusproduced, each of which is confined above and beneath by parts of bothof the flanges or walls 20 and 21, throughout approximately 120 of acomplete turn around the core 19. Each such passage at its lower endleads into an inlet zone confined at the top by a portion of a.

closes the passages between the flanges or walls 20 and 21.

The core or body 19 is surfaced ofl' plane at the bottom and into thesame merge the lower termini of the flanges or walls 20 and 21; and theupper end of the core or body 19 extends in reduced cylindricalformation slightly above the upper termini of the flanges or walls 20and 21 as at 19: and such core or body 19 is finished off above suchportion 19 in a truncated conical head 19 the upper face 19 of which isplane and of a circular formation slightly smaller than that of theoutlet or discharge opening 16 in the top of the head 12 with which itregisters.

The member C is mounted upon the member D, and comprises an annulus 23which surrounds the core or body 19 immediately beneath the truncatedconical upper end 19* thereof, being rotatively mounted within andconfined by the walls of the reduced portion 19 This member C furthercomprises diametrically oppositely projecting shutter vanes 24: each 0which is segmental in formation and extends substantially through 90 ofthe same circle, whereby they may both be positioned to entirely closethe outlet zones of the two channels between the flanges 20 and 21 ormay be so positioned as to entirely open such outlet zones.

In the top face 19 of the core or body 19 is produced a recess or socket25 for the reception of a suitable implement to enable 7 vantagessprinkler organized to embody the inven-- the member D to be adjustedwithin the member B, by means of the screw threads 22 and 18.

The operation, method of use and adin service of the improved tion willbe readily understood from the foregoing description taken connectionwith the accompanying drawingand the following statement :With the partsin the relative positions shown in the drawing, water rising through thelower orifice 7 of the shell A, from the service pipe, will enterthechannels between and confined in part by the helical flanges or walls20"and 21 and in part confined by the inner wall of the tubular body 9,and will ascend, entering through the inlet zones at the lower ends ofsuch channels, and emerging from the outlet zones at the upper ends ofsaid channels, the shutter vanes 24 being disposed so as not to obstructsaid outlet zones. In its upward passage through 'such channels, whichare of helical formation, the water receives a torque or twist ortendency to whirl, and this tendency is preserved as the water rises atthe sides of and flows over the truncated conical top 19 of the core orbody 19 and finds its way out through the discharge opening 16 in thehead 12 of the tubular body 6. The out-rush of the water is tangentialto the whirl within the opening 16, and spreads laterally ina relativelyflat fanlike formation, the degree of flattening of such jetbeingdependent upon the relative separation of the truncated conical top 19of the member D and the head 12 of the tubular body 9.. The member D isadjustable to a material degree within the body 9, by means of theco-engaging threads 22 and 18; and the more remotely such member D beadjusted from the head 12, the higher the jet or column of water willrise in its laterally arching discharge from the opening 16. If themember D is brought into close proximity to the discharge opening 16,the jet or colum of water discharged will be substantially in-the formof a flat sheet extending outwardly from the sprinkler, or having thesprinkler as a center, and covering a wide area of lawn or otherformation. The adjustment of the member D with respect to the dischargeopening is conveniently performed by introducing a suitable implementthrough the discharge opening and into the recess 25 in the top 19 ofthe member D'. The amount of water which is passed upwardly to throughthe channels around the member D may be varied by adjusting the memberC. so as to close to a greater or lesser extent theoutlet zones or upperends of such channels by means of the shutter vanes 24.

The device is manifestly capable of such adjustment and control as toproduce the the discharge opening particular formation of emitted water001- umn or jet so as to conform the same to the particular lawn area orother surfaces which it is desired to sprinkle or spray; and the entiredevice is of few and simple parts, not

liable to get out of order or to deteriorate in long use. A

The head 12 may the surface of the earth of lawn, as indicatedfragmentarily kler presents no projecting portion for obstruction orinterference.

It is manifest that by bringing the member D at its truncated conicaltop 19 up he installed flush with in Fig. 1, so that the sprincloselyinto engagement with the head 12, such truncated conical top willentirely close the discharge opening 16 and shut oil the-flow of waterthrough the sprinkler.

We do not desire to be understood as limiting ourselves to theparticular provision, formation, construction, combination, associationand relative arrangement of parts,

members and features shown and described;'

comprising a casing provided with a discharge cpening,a member withinthe casing adjustable toward and away from the discharge opening, saidmember having spaced peripheral flanges threaded to the casing, and aperipheral helical passage being provided in the adjustable memberbetween the flanges, through which passage water may be passed to saiddischarge opening.

2. A device of the character described, comprising a casing providedwith a discharge opening, a member within the casing adjustable towardand away 'from the discharge opening, said member having spacedperipheral flanges threaded to the casing, and a helical passage beingprovided in the adjustable member between the flanges, through whichpassage water may be passed to saiddischarge opening; and means forvarying the amount of water traversing said passage.
